Though
ensuring acceptable and standard application delivery has always been
a crucial aspect, historically it was never a top priority for IT
enterprises. It underwent a change many years back when the IT
organizations started to focus in a dedicated manner on application
delivery on a huge part of responding to the performance challenges
related to supporting applications that were in turn delay sensitive
and supporting huge file transfers between branch offices and
headquarters. A major medium through which IT enterprises were
responding to these performance challenges was by implementing WAN
optimization controllers.
In
most cases, WAN
optimization controllers were
deployed as a “stand-alone” hardware-based device. Owing to the
mass adoption of Virtualization, IT enterprises today are witnessing
a new kind of application delivery challenges. For instance,
successful desktop Virtualization is a crucial factor that will
compel IT enterprises to support a significant increase in delay
sensitive WAN traffic. In order to aid this situation service
providers specializing in RDP remote
access have introduced WAN optimization controllers with multiple
features, that helps in:
*
Minimizing the remote application response times by up to 95%
*
Minimizing the network bandwidth utilization by up to 95%
* Is
purpose-built to bring down the impact of network congestion, latency
and packet loss that combines to significantly slow end-user response
times
* The
Application-specific WAN optimization blueprints and specific
protocol optimization helps in reducing redundant, chatty protocol
traffic
*
Stream-based differencing averts transmission of content already in
the local data store and the compression techniques minimizes the
amount of data on the wire
* Is
available in hardware and virtual appliance form factors, that helps
to achieve ROI within a less time frame
*
Supports 50% more speeded up connections
* The
virtual appliances make use of minimal system resource, can stay with
other applications and scale linearly with the addition of CPU cores,
memory and disks
*
Helps in easier management of virtual and physical deployment,
transparent addressing, statistical performance dashboard and auto
discovery
*
Offers centralized provisioning and management by incorporating with
Virtualization management systems
Furthermore,
advanced WAN
optimization controllers
make use of a combination of application
acceleration,
packet compression, network acceleration, protocol optimization and
caching to speed up the applications and minimize the expense of
delivering applications across wide area networks.
